' SWITCH-HOOK-CQNTROLLING DEVICE.

v Specification of Letters Patent. Patented Aug. 31, lgtltll.

Application filed October 2911908. Serial Ito. 460,061.

To all whom 'it may concern:

Be it known that I, Mose MOSLER KAHN, a citizen of the United States, and 'a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Switch- I llook-Controlling Devices, of which the 01- lowing is a specification.

My invention is an improvement in switch hook controlling devlces, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

The object of the inventionis to provide a device for engaging the receiver hook, when the receiver is sup 'mrted by the adjustable support shown and described in my previous patent No.- 898,898 dated Sept. 15, 1908.

Referring to the drawings forming a part hereof Figure 1 is a side view of a wall box provided with the improvement, Fig. 2 is a iorspective view of "the improvement, the

parts being separatecL-and Fig. 3 is arfront tion, the device is shown applied to'a wall box" A and connected with the transmitter arm, is the receiver support 13, having a clamp l), for engaging the arm, and a rest I),

hook or yoke when thetelephone is not in use. The arm comprlses a bracket 0, having 'through one end a hole for receiving a screw r: whereby it may be attached to thevall box or other support, and at its other end a threaded opening The arnrC is provided atone of its ends -with an opening, through which passes a thumb screw 0, the threaded end of which passes through the threaded opening in the bracket or support (,and the thumb screw is provided with a pin passing trans vorsely through the head of the screw, for convenience in manipulating thesame. The opposite end of the arm is provided with an opening o through which passes a screw 0 In the present embodiment of my invenhaving a washer 0, arranged between the head of the screw and the arm, and the threaded end of the screw engagm a threaded opening in a cylindrical weight a, which weight is adapted to rest on the hook or yoke as the case may be, for retaining it in closed position. The free end of the weight is provided with a threaded opening, in which screws the threaded stem 0", of a grip the grip being provided with a shoulder c for engaging the end of the weight.

In operatiomthe weighted arm normally rests upon the hook or wei ht in the position shown in Fig. 1, in fu-l lines. when however, the telephone is inuse, the arm is thrown backwardly into position shown-in dotted lines in the same figure, and maybe,

secured in this position by means of the set screw. After thetelephone has been used, the arm is again turned forwardlyl in'to engagement with the hook or yoke.

It will be observed from an inspection of Fig. 2, that the ends of the arm C are olt'set from each other, in ortler to permitthe tree end ofitsarm to clear theslde. of the wall box. i

I claim:

1. A device of the class described, comprising a bracket provided atone end with an opening whereby it may be attached to a transmitter support, and at the other with a threaded opening, an arm provided at each end with openings, a set screw passing through one of said openings, and engaging the threaded opening of the support,,a cylindrical wei ht provided at each end with a cylindrici l opening, a screw passing through the other opening of the arm and engaging one of the threaded openings of the weight, and a grip having a threaded stem engaging the other opening.

2. A device of the class described, comprising a bracket for attachment to a transmitter support, an arm pivoted by one end to the end of the bracket, a cylindrical weight connected with the other end of the arm, a grip on the weight, and means for fixing the arm with respect to the bracket.

I MOSE MOSLER KAHN.
